[Q] USB Mass storage mode not working after root

After the root procedure I don't seem to have any ability to use USB Mass storage.
Windows reports it as an empty drive, linux will show the device as connecting and assigns it a /dev/sdx device, but when you attempt to mount or fdisk, it reports no medium.
Any one else having similar issues?
I could always try a reset to factory defaults after unrooting, but I really don't see what rooting could have done.
I used the manual method and had to run zerg several times, however beyond that no other files where modified.
I've already reverted /data/local.prop to stock, no help.
Any one have any other insights?

I had to uninstall motohelper to get USB mass storage working.

When you take a picture, does it save to your sdcard? Sounds completely unrelated huh? Well, this phone seems to have an issue with the sdcard randomly becoming read only. I have had that issue multiple times now and usually it's solved by restarting the phone. Well, I seen your issue today and didn't remember if I had tried to use it as mass storage since rooting it so I tried....no luck. Took a pic, it looked like it saved, didn't get any error, but could not find the pic in my gallery. Then I tried to take a screenshot and got the read only error. So I just took my sdcard out and made a copy of it to my pc, put it back in and rebooted my phone, it's all good now, imagine that. Needless to say, i'm backing up all my apps right now before doing anything else. Then gonna backup my contacts too.

motohelper... Sounds like a stock app...
did you just rm the apk?

No.motohelper was a bs program that got installed to my PC when I downloaded and installed the driver pack from Motorola. Until
I uninstalled it I couldn't get USB mass storage to work.phone portal would,but not storage.

I had to reinstall all the drivers through motohelper to get it to work as well =/
No problems now though~

I was able to get my sdcard recognized again but still could not use it as mass storage device, never had a problem with this before root. Did factory reset and all is well.

There is no possible way root caused the issue at all. It stopped working for me once I installed moto drivers, but shows the device with mass storage under it in usb portal mode.

Well then it's one hell of a coincidence! Before root, w/motodrivers, worked fine, after root w/motodrivers, didn't work, after unrooting, w/motordrivers, works again.

Same thing happened with my phone. Actually now returned because of all the issues I kept having hardware wise and wound up going and getting the HTC Vivid. So if any of yall switch I will see you when a Forum is made for this device.

I have until the 24th of this month to decide if I want to keep this phone or not. I unrooted yesterday, will see how it goes this week. I'm not trying to pay big money for a phone right now so we'll see how it plays out.

OK I give up. The problem is intermittent. I'm going to do a log cat next time cause I'm getting about irritated. SOme times it works fine some times not. I've not unrooted or changed anything since the initial problem.
The only thing I can possibly thing is that some of the commands installed by busybox is screwing up the works.
Short of that nothing REALLY changes that could affect the operation of the phone.
What doesn't bare that idea out however is the fact that it EVER works.
**STUMPED**

It does the exact same thing on a completely unmodified phone. Therefore, it's nothing you did to it that's cause the problem.

I have the same thing on mine but it was something with the format of the card.
I flipped it to windows media sync mode then backed up the card and after the backup I unmounted the card and let the atrix format it.
I had the card in a atrix 1 before I put it in the atrix 2 so I do not know if this is the case or not.
This has now been working with out a problem for 4 days now

Same thing happened to my phone, I never rooted it.

Confirmed user error.

Thank you seraphielx! Shortly before finding this thead, I'd noticed that I had a rather large number of files in the LOST.DIR on my SDcard. Which coincided with the seemingly random disappearance of some of the apps I'd moved there. And when I pulled the SDcard to back it up on my PC, there were nearly 600mb worth of files in the LOST.DIR. Most of which were photos, plus (I think) some apps. Thank God I make regular backups!
I believe the problem, at least in my case, has to do with the fact that I could pull the SDcard without first pulling the battery; which I did when I swapped the stock 2gb card for my 32gb card right after I bought the phone. Thus corrupting many files, and probably the file system on the card as well.
After backing up what remained of my storage files, I tried to format the SDcard in the Atrix2, but It wouldn't let me select the option to format, and neither could I unmount the SDcard. So I powered down the phone, pulled the card and formatted it from my PC. Poped it back in the phone, powered up, and was then able to format it with the Atrix2. Since then I've had no issues with accessing usb mass storage, nor with disappearing apps and photos.
Thanx again for the assistance!

For me sometimes it takes a few minutes before I can access sdcard from PC.
Usually it works instantly after phone reboot while not plugged in pc, then it takes ages...

Update: OK, I can't unmount my SDcard, again. Which, of course, means I can't access usb mass storage anymore. The only I've changes made since my last post were to install some apps and change some status bar icons via Rom Toolbox, and I can't believe that has anything with the issue.
If I do a factory reset, will I need to root again?

If you have any apps installed on your SD card you will continue to have problems.

Galaxy Note 10.1, USB Mass Storage Mode, Questions and Options please?

All -
Okay, USB Mass Storage mode, what about it?
My Galaxy Note 5.3 with ICS has it. My Galaxy S3 with ICS does not have it.
I've been Googling for hours, and getting nowhere. The Samsung website says the N8000 has "USB Mass Storage Mode". But two posters on XDA say that it does not.
What I like to do is keep my PC file directory synced to my Samsung device. On my old Galaxy Tab 7 Classic, I can just plug it in (USB Mass Storage Mode), and it mounts and works. I then use ROBOCOPY (Windows rsync wannabe) and it syncs up just fine, and very quickly. I've got it in a batch file, I just plug in, double-click the icon, and it goes.
On the S3, MTP mode, as everyone seems to already know, doesn't cut it at all. It can't detect dates or metadata, so it wants to re-copy everything, in very slow MTP mode. UGH!
Prior to the ICS update for my note 5.3, I just rooted and used Samba.
So my questions:
1. Can someone definitively confirm whether the GT-N8000 Galaxy Note 10.1 has true USB Mass Storage mode support, or not?
2. If not, do we think Samsung is going to add it, as they did with the Galaxy note 5.3?
3. If not, is Samba the right way to go here? Is there a better way?
4. I've heard that "Airdroid" might be good, but does it support syncing a la rsync or robocopy?
5. Does anyone have any thoughts on how to proceed?
Thank you all so much for your patience and guidance!
Glen

My Galaxy S2 has USB Mass Storage mode... and I'm very dissapointed that the Note 10.1 does not have USB Mass Storage mode. Why do they keep changing these file structures... its so inconsistent.
One of the reasons I jumped from Transformer Prime TF201 to the Note 10.1 is because I thought the file structure in the Note 10.1 is better sturctured, just like the S2.
Anyone has any work around this? I do not want to always remove my microSD card all the time.

In settings/developer options, select usb debugging. Then when you connect to pc you should get mass storage hookup

You just need the MTP drivers .........
On WinXP machines mostly You will have to download KIES , install it to get drivers installed but not run it, connect 10.1 via USB and voila You will have a folder showing "phone" and sdcard folder.
Now You can use the sdcard card as mass storage. Only when it comes to transfer of files not recognized by Android or the device it will ask You wether it should be copied , just click yes.
On most win7 pcs Sammy devices are recognized automatically as MTP ...........

Same issue here , and for windows 8 i can't get the right drivers for it , the pc can't recognize the device in case i installed last version of Samsung Kies

The Note 10.1 uses MTP like the S3. I used this -> http://forum.xda-developers.com/showthread.php?t=1711009 on my Note 10.1 and it lets me mount the external micro SD card when I plug it into my Windows 7 computer. You have to be rooted w/ busybox installed. It should work for the S3 also, since that is what it was made for.
Good luck!

go to settings...
I'm running ICS 4.0.4 on galaxy note which runs MTP mode by default.
Usb mass storage mode can be enabled from settings-> wireless and network (more) -> usb utilities... turn on mass storage
There u r... hope it helps

is there a mod for the note 10.1 for ums?

Bump for an old question -
Is there a working solution for USB mass storage mode that works well with our note yet ?

If you are able to mount the internal sd as card in your pc then you should be able to do it, since it would be acting like any other hard drive
I dont think this is possible with stock firmware.. but if you are able to install an asop rom like CM then you might have option to do it by using some app like ums mass storage enabler or so..

[Q] [HELP] All my media (photos,videos) except rintones are deleted!

Hi Guys,
I'm utterly confused as to how can (only) all my photos and videos be selectively deleted from my phone!
From both my internal sdcard and external sdcard, only my pictures (of any format and in any folder) and the videos have been deleted!
I had connected my phone to my laptop in the MTP mode. I was trying to create a folder on my external sdcard. I tried to rename that folder to 'Books' but in-spite of my repeated tries it was still staying as 'New Folder'.
So I disconnected my phone and now connected it in 'USB storage' mode. This time I could see the 'New Folder' and rename it and copy the stuff I wanted to copy.
But suddenly I realised that the free space on my phone had increased!! I didn't know how then and I left But later in the night when I decided to change my wallpaper, I found out what had befallen me. But still clueless how and why this has transpired! :crying:
I'm running Avatar ROM 2.8b and Butter Kernel 1.3 stable.
Thanks and regards,
Nakul

Connect your phone in UMS mode to PC and try Recuva file recovery software. I have used it many times and am very satisfied with it.

i am on cm10.1, my phone is not connecting through usb cable ( usb device not recognised) and my sdcard0 is unmounted. i mounted the data through cwm. but it still reverts back to unmount on it own. nothing is showing up in filemanager. i have tried everything(reinstalling drivers/formatting/reinstalling cm10.1....and lots of rebooting with experimenting here and there) in my prowess but nothing came of it...its to the point of exhausting and irritating.....kindly help me please.
thanks

ZIP/RAR files transferred to ZUK Z2 turn out corrupted(CRC error)

Basically if I download a zip/rar file via wifi or transfer it from my PC via cable it almost always turns out that my zuk z2 has corrupted it (CRC checksum error). I have flashed and done factory reset. Tried it on vendor rom (2.0.093st) and now on official 2.0.133st with the same issue. I did not have this issue 2 weeks ago. The phone is barely a month. I also noticed freezing and blinking led light issue around the same time, not sure if it's related.

Transferred files getting corrupted are often times a result of the storage medium itself (your Internal/External SD card) being corrupted. And not necessarily a buggy ROM. Try formatting your device's storage and see if that solves your issue.

I flashed it and then did a factory reset but still had the same issue. It's the internal SD card of the phone, no option for external. I have never heard of internal SD card of a phone being corrupted before, lately I have been having some hang ups involving the phone going black with the led flashing repeatedly. Do you think they could be related

A factory reset doesn't normally erase the internal SD. Only the internal storage. Because then all your files (including your media) would've gotten erased every time you did a factory reset.
If the led is blinking repeatedly regardless of the ROM, then it might be a hardware defect. And similarly, even though corrupt internal SD cards are rare, it is possible. OEMS cut corners sometimes in order to keep costs down. Especially when they try to put "top notch" specs in an "unbelievably cheap" phone.

Go to settings->storage and the option should be in there somewhere.
Ensure you backup/transfer all your files to your PC first though.
And you can use this app (if it doesn't continuously crash on your device :silly: ) to check whether or not there's actually a problem with the internal SD before doing the full format.

App called rar made by rarlabs creators of winrar. I also copy the rar/zip files back to my pc and test on winrar as well to confirm it is corrupt and it usually is.
